Thanks for posting the question to the forum. When ActionEventOnMatch is set to true, once the criteria in the filter is triggered, an event is raised and/or the event is stored in the AMT event log. Although there is a caveat to how many event logs are stored in the NVRAM.
Because of this for a statistics type of filter, there is no need for logging many events. And in your case even though the packet count is 200, you are not seeing that many event logs.
Hope this helps.
